Maybe the quadrifilar helix.

That is made for a single circulation signal only.

Then it's a point driven against ground that you need. Or a 2 point
dipole. Either one with a lossless transmission line would work.

That's the only thing that will do all you want and do both RHC and LHC
polarizations and do it at all frequencies. I have to assume you want
all frequencies since you haven't responded on that question.

And it will have a very unusable impedance at all frequencies. But if
you can do the lossless line, you are probably covered on the lossless
tuner, too.

Good luck. You want everything, and you can't have it.

And "single circulation" is not the proper terminology (as usual),
although I am somewhat sure about what you meant.
